Our 4108M runs a little hot. After replacing the entire
cooling system and
exhaust, I am focusing on the gauge and sender.
I have noted that the gauge is VDO but the sender is WEMA.
Sender is stamped
M14X1.5 150124 WEMA
I have heard that VDO gauges should be paired with VDO senders.
(Q) could this be a mismatch causing the error?
Second thing I tried was a IR gun on the sender. The temp gauge reads 91. The hottest I could get on the IR gun on the sender was 81. I would expect a little digfference but not 10 degrees.
(Q) What difference might one expect between the top of the sender and the temp measured by the sender in the
coolant?
